Amit Singh has added support for a whole bunch of early UNIX filesystem and
archive formats to FUSE.

Does this depend heavily on OS X, or should it work on Linux and BSD as well?

No idea. I had a brief look at some of the code on the web site and it seems
relatively neutral, but I have not downloaded it yet. I've sent an e-mail
with the same question to Amit.

OK, a checkout and compile-attempt later I can tell you that it doesn't 
cook directly out of the box into the pot. Should not be that much magic 
to get it cooking thought.

Amit says:

  As for portability, yes, I have kept AncientFS limited to the cross
  platform FUSE API (MacFUSE supports much more than the FUSE API). So,
  it should work on other FUSE implementations with few changes.

I've modified the code so compiles on FreeBSD but dlsym() still does not 
work: 

root at nudel ancientfs> ./ancientfs --type v7 --dmg v7_rl02_1145 /mnt/tmp
Undefined symbol "unixfs_v7"
invalid file system type v7
Exit 255 

dlsym() is kinda new to me so I'm a bit lost... 

I've uploaded a diff to the svn checkout which is mentioned on Amits page 
here: 

http://pofo.de/tmp/ancientfs_20081218_01.diff 

The changes are
 - casting to satisfy %llu and %lu printf
 - Makefile adjustments
 - enhance endian checks to support BYTE_ORDER
 - work around undefined OSSwap functions

I keep meaning to poke about at FUSE, since it plays more or
less the role of the file-server-implementation library setup
I wrote for my own purposes 20 years ago (in the context of a
UNIX variant that cannot yet be distributed freely).

But I'd be surprised if the stuff was terribly MacOS X dependent.
Certainly FUSE exists in Linux, and the libraries and requisite
kernel module are even included in some Linux distributions
(notably recent editions of Fedora), because sshfs is built atop
FUSE.

"Cannot yet" is good.  Is there any hope of seeing the 10th Edition
emerge from the shadows, ever?
